Abstract
An encoder includes a precoder for encoding an input information object according to a preset encoding scheme and storing the encoded information object in a precoder buffer, a sample number/address generation unit for generating a sample number of each sample and an address, which corresponds to each bit of each sample and the address of the precoder buffer, a multiplexer for selecting a bit of the precoder buffer corresponding to the address generated by the sample number/address generation module, a sampling buffer for storing a bit of each sample output from the multiplexer, a control packet generation module for generating a control packet including information on the sample number generated by the sample number/address generation module, a packet assembling unit for assembling the sample stored in the sampling buffer with the control packet generated by the control data generation module, and a modulation module for modulating the packet output from the packet assembling unit into a sound signal according to a preset scheme.
